John Lindgreen HansenAPFLA both is a very easy and at the same time an efficient method for pain free local anasthesia. Today there is a lot of machines that offer pain free local anasthesia. This method can do the same without big investments and it saves time too. But most importantly of all the patients love it! The metod is easy to learn.

All teeths can be numbed without exception. It is also safe because you don’t come into close contact with vital nerves because there is no need for a block. The different techniques in APFLA is nothing new – they have been known domestically and abroad for decades. What makes APFLA something new is this method combines these techniques and makes a good and reliable method for pain free local anasthsia.

We have used this method at Strandvejens Tandklinik for more that 10.000 procedures since 2006 and we have numerous happy patients who really appreciates Pain Free visits to the dentist. Im sharing this method with anyone who is interested. This is my way of repaying a little bit of my debt of gratitude to all generous colleagues who have shared their knowledge with me.

My wish is that you will use this method to the benefit of your patients and share it with colleagues to the benefit of even more patients.

With my best regards

Technical stuff


  • Septanes w adrenalin 1/100 000 (articain, septodont)
  • Henke Ject
  • Standard syringe

The method

With a firm grip take hold of the patients cheek/lip and make a quick shaking motion so that the whole cheek is moving and apply 1/2 tubule as infiltration in front of tooth in question. Do not inject before you have begun the shaking motion.

Count slowly from 1 to 15 while injecting 1/2 tubule. Switch to the Henke Ject and do 4 intra ligamentary injections at the four ”corners” of the tooth slightly approximally. You start with the 2  buccal corners then the 2 lingual corners. The injections has to be done slowly with a steady squeeze. It should take no less than 5-6 seconds per corner.

It is very important that you can feel resistance while injecting. If there is no or very little resistance then it means that the liquid is escaping the ligament/periodontal pocket. Then the tooth will not be numbed. Instead move the needle slightly to one side and try again.

Repeat until you find adequate resistance. When you have injected at the four corners the tooth is numb and you can start working on it immediately. That way you can save the 3-5 minutes wait before beginning to work as you do with a traditional method.

Do also check out the instructional video. I find the Henke Ject more suitable than e.g. a Paro Ject because it can generate a much higher pressure. I have no affiliation with any of the products mentioned for this method.
